Dilip,

Mark said the approach, starting with C# 10, would be to use the CallerArgumentExpressionAttribute. He’s writing a blog about this very subject that you should see on our blog in the near future. Thanks for the read!

string formatter(Message msg, Exception ex)
{
var content = $”[{logLevel}]\r\n{msg.Title}\r\n{msg.Body}\r\n{msg.Author}\r\n{msg.CreatedDate}\r\n\r\n”;
return content;
}
log.Log(logLevel, new EventId(), message, null, (msg, ex) => formatter(msg, ex));

where Message is a custom object -> in yout custom provider, “TState state” parameter of Log method will be your passed object

// Write log message
myCustomLogger.LogError(“My Message”, customDataObject);

// Log method implementation
public void Log(…)

In other words, How do I read customDataObject in above Log method?

Thanks in advance.

Agreed.. this doesn’t actually improve on the original at all.
